My father gave me his old samsung 40b8000 led tv. Picture was good. Then I was fool and updated firmware to last one ( T-CHU7DEUC-3002.1 date 21.04.2010). Also I changed some settings from secret menu because i wanted to turn off local dimming. Now picture is realy ugly, dark, i cant watch my sd channels because it is too dark and colours are strange (even in dymamic mod with backlight 10). Please help me and tell me what i can do to return back good picture. Thank you so much

You can do factory reset and get all sm values back to defaults. Wait for anyone who could post service menu pictures of same or similar TV.

Do you think that rollback firmware to T-CHU7DEUC-2009.0 will help to get better picture quality?

If your "Alternative software" submenu is active, you can try. I doubt it changes something.

Juusso, i found service manual on net with default service menu values for samsung b7000. Is it same like samsung b8000?
